Maybe. Again, only an experiment will get a definitive answer. Tumble the jbullets in
airsoft pellets with a dollup (scientific measure) of JPW. And for cast, too.
I think I'd like chrono NuFinished and JPWed jbullets against dry, aside from the possibility
of the reduction of copper fouling, and possible accy increase
(or decrease ).

I just put the cast in a baggie with a drop of the nufinish and rolled that all around.
took them out and let them dry, then just buffed them off with a rag.
they have been just sitting there, since I keep hemming and hawing on whether to shoot them as is or to check them or lube/check them.
they only been sitting there for 2-3 years now.
the issue is the rifles I'm not scared to shoot them in probably won't show the difference and the ones that will are kind of my pet rifles.

That was Felix's idea originally. I took the idea and ran with it to make a variety of successful greases from polyethylene, polypropylene, and polystyrene, but never really tried polyester. Axel Christiernsson developed a fantastic high-speed coupling grease using PP which would not centrifugally separate, but all those polymer greases have a low drop point and I found that in shooting, they leave a plastic coating in the bore. Polyester makes good jacket when cross-linked. Polyolester two-stroke oil made into a thick, adhesive grease with HDPE and fortified with 5 micron hBN makes a really good trigger/sear/lock lube. Johnson's One Step works well on copper jackets at low speed, improving SD's and groups, and I have a feeling that it would work well as a high-speed coating too, even without the LLA. Nu-Finish didn't work well for me when dehydrated and mixed with LLA, put in a naptha carrier, and used on lead bullets as a coating lube (got bad leading). That's about all the experience I have to share regarding plastics and bullets, the low melt point of most polymers seems to be the limiting factor as a lube, but a thin coating might make all the difference, just as it did for Bill's pyro cylinder.
Yep. Why eliminate copper fouling just to deal with a different, possibly worse, fouling instead?
One advantage, if you can call it that, is that we k ow lots about copper fouling. We know what it does to accuracy and how to remove it. Removal is easy with common solvents.
Plastic fouling would likely be easy to remove with common bore solvents but we don't know? Is it cumulative or self limiting?

All good points I agree with Brad.
I want, and look for, a certain ambidexterity quality between jacketed and cast. I would like the luxury to switch back and forth at my will with NO ill affects in doing so. I will not trade copper fouling for any sort of plastic induced abnormality in my bore for sure! Each will have to ride over the other's 'deposits' without any detriment in doing so! Maybe C.O.R.E. compatibility??

One condition bothers me for the change up........ Hunting big game in a grouse rich area. A cast grouse load shot over a fouled jacketed bore along with cold start sometimes is off enough to miss a 50 yard grouse. Some may say use a light jacketed load for grouse......
I haven't shot a grouse with jacketed....EVER! That though borders on sacrilegious to me!

plastic I can deal with, I deal with a little plastic fouling in my shotguns all the time..
one thing about the NuFinish is it does come off.
if I don't re-coat the car at least once a year I can see the water stop beading up and start to sheet off the car.
I know it ain't getting 52 washes.
the only thing I am real concerned with is build up or it doing something weird from it combining with the powder fouling.
